A week a go i had my wheels road forced balanced and they insisted that I had a bad tire and it needed replacing. Well I had it replaced.

Now my car shudders from 62-80mph

I had an indy replace my drive belt tensioner, Oil filter housing gasket, and mecatronic seal and they also replaced my tranny fluid.

Now my issue is I asked him to check my wheel bearings and he said they are fine. So now I am at a lose whats causing the shudder. It can be seen in the wheel too it moves left to right.
I am beginging to think i should just replace my rotors. They dont feel warped but what else could it be at this point.
